In one spectacular incident, a black 4x4 comes to a shuddering halt on a bollard. A man leaps out of the vehicle to inspect the damage as his partner unstraps a child from the back seat and walks away.

Speared

In a second incident - reported by the M.E.N. last week - Natalie Kelly, of Denton, who has a disabled badge, waited until a Metroshuttle bus drove past and the barriers dropped - only to spear her engine when she drove behind it in a failed attempt to get through. Ms Kelly admitted: "Yes I saw the warning signs. All I wanted to do was park in a disabled space."

The city council installed the bollards on a trial basis because of the street's high casualty rate. They have no plans to change them before the trial ends next year - and want to keep them.

Coun Neal Swannick said: "There is no time to sneak in behind a bus. The message is: Don't do it."

ARE the bollards a danger - or a good way of controlling traffic? Have your say.
